New well logging-control technology in educational process
In order to familiarize students with the methods of assessment and selection of measuring equipment used to conduct well geophysical studies, a set of trainingstands based on digital technologies with the use of up-to-date software and hardware was developed and successfully applied. These stands allow to explore the processes of obtaining and converting date using multifunctional highly productive digital devices. Since the stands are made according to a unified USB device scheme, this allows to reduce the use of unique specific software products when performing parameter measurements, telecasting and processing the received data by using public software such as Excel, Word, Paint
Identification of development of highly productive reservoirs based on geomechanical modeling process
In complex deposits with large angles of bedding and a sharp change in the thickness of the seams, zones of nonuniform stresses, leading to rock deformation, are formed. To identify such zones, various methods are used, one of which is geomechanical modeling. In the course of this work, a geological-geomechanical model of the productive reservoir of the oil field was constructed, over which areas with apparent extremes of stress concentrations were identified. The analysis of the wells performance and logging data showed that in areas with maximum stress concentrations rocks start fracturing, which results in a sharp increase in the productivity of the wells
Information and technical support for reservoir management in national oil and gas producing companies
A systematic approach to reservoir management at a vertically integrated oil company is presented, the informative value and effective implementation of the permanent reservoir monitoring is described and the results are shown, which are expressed in the production and field recovery increase
Identifying parameters of porosity change in complex reservoir after clay acid treatment
Currently, the deposits located within the Fedorov dome structure are at the final stage of development. The share of complex projects under construction containing difficult-to-recover reserves is more than 98 %. All reservoirs are characte- rized by low natural permeability, high clay content, significant water retention ability and heterogeneity in mineralogical composition and reservoir properties. It is important to note that the heterogeneity of rocks in the content of carbonates is generally low and medium, while a complexly built reservoir often contains interlayers with a high content of carbonates. In such conditions, deposits are developed using the technology of clay acid system treatment (aqueous clay-acid compounds with boric acid additives) without prior removal of carbonate compounds
Weathering crust of basement of southern part of Nepsko-Botuobinskaya anticline for prospective exploration for oil and gas
This article is about the structure and composition of the weathering crust of the basement of the southern part of the Nepsko-Botuobinskaya anticline. The authors classified and named the rocks composing the upper part of the crystalline basement according to the 3rd edition of the latest Petrographic Code of Russia, published in 2008. In addition, reservoir properties of weathered rock were estimated. The question about weathering rocks as a prospect for oil and gas exploration was discussed
Prospects of using downhole georadar for geonavigation while drilling oil and gas wells
The analysis of the current state of exploration of the geological environment by borehole georadars is made on the basis of which the prospects for using the available modern technical solutions and techniques for processing and interpreting the information are given. These are adaptated to oil and gas fields during well construction. The main physico-geological models of productive layers, characteristic for the geological structure of gas, gas-condensate and oil deposits, are considered. In the process of work, modeling was used, including the use of special physical models. Based on the results of the research, conclusions were drawn about the most optimal way of development and introduction of a new technology, i.e. the creation of an instrumentation and methodological complex for geonavigation of well bores using georadars
Accounting for influence of asymmetry of horizontal wells placement along reservoir to plan number of wellsto be drilled
We have analyzed the effect of asymmetry of the horizontal wellbore placement along the reservoir. Studies of the location of horizontal wells have shown that the performance of such wells will vary significantly with the thickness of the reservoir, as this is predetermined by increased distance from the horizontal wellbore. The authors carried out the necessary gas-hydrodynamic calculations to use these to design the development of gas and gas condensate fields with different capacitive filtration properties. The results of these calculations are given in the article in tabular and graphical forms, which can be used in practical calculations to determine the number of horizontal wells to be drilled, taking into account the asymmetric placement of such wells in the reservoir thickness
Сalculation of anti-icing system of heat-exchange section for integrated air-cleaning system of gas turbine engine
Protection of the inlet air-cleaning system of the gas turbine engine from ice formation is an important aspect of the operation of the gas-compressor unit during the autumn-winter operation period. The article presents a comparative analysis of the existing methods for the implementation of anti-icing systems, describes their advantages and disadvantages. A method for thermal and hydraulic calculations of a modernized anti-icing system using a heat-exchange section is presented. Gas pumping unit GPA-C-16 is used as an example for the calculation and design sketching
The update of topographical plans in order to bring the information displayed on them in accordance with the current state of the area and construction in engineering surveys for construction
At present, often enough during engineering and geodetic surveys previously created engineering and topographic plans are updated to the current state of the terrain and buildings. The update may be required when using as initial the survey data obtained at the previous stages of urban development, if more than two years have elapsed since the survey, during surveys in the winter with snow depth over 20 cm, with changes in the terrain of more than 35%, or when the survey is conducted in two stages. Despite the apparent simplicity, in the pro-cess of this type of work techniques and technologies that areprescribed by regulatory documents are violated. The authors consider the issues of compli-ance with the requirements of technical regulations and sets of rules when updating engineering and topographic plans. Recommendations are given for improving the procedure for the accumulation of archives of engineering survey data and state supervision of their use
Сhecking quality of welded pipes for gas pipelines for compliance with static and dynamic crack resistance normative requirements
The article considers a new system for quality assurance of large diameter welded pipes for main gas pipelines in terms of fracture toughness. We propose to use the existing quality assurance system for tubulars for oil and petroleum products pipeline transport. It is proposed to use static fracture toughness and long crack propagation resistance as the normalized fracture toughness parameters, These have not been previously used for main gas pipelines
Effect of heat removal into pumped product on pipe wall temperature gradient during the welding repair of corroded pinholes
Currently, welding is the most progressive method of repairing local corrosion damage on the outer surface of the linear part of the mains. However, heating of the pipe wall by welding, which occurs due to the action of a concentrated source of heat (welding arc) softens the metal of the repaired surface, which creates the risk of an emergency. The authors present the results of the studies of thermal processes occurring in the pipe wall repaired by welding. The authors have identified the zone of guaranteed strength properties, providing a reserve for temporary resistance to metal pipe rupture during repair, and also established the relationship between the thickness of the specified area and the amount of running energy and heat removal into the pumped product during repair. A mathematical model describing the polynomial dependence of the thickness of the zone of guaranteed strength properties on the effective thermal power of the welding arc, the speed of its movement and the residual thickness of the pipe wall at the repair site are presented
Technical means of measurement and accounting of oil and oil products losses
This article assesses the methods of determining the amount of oil and petroleum products stored in tanks or transported in oil tankers and railway tanks. The shortcomings of various methods of determining the amount of oil and oil products, as well as accounting for losses are analyzed and identified
Development of competitive-oriented standards for import substitution programme of oil and gas facilities in Russia
The paper discusses the advantages and disadvantages of the procedure for harmonizing national standards with international standards. It also analyzes approaches to updating Russian standardization documents. The author substan- tiates the necessity to develop fundamentally new domestic documents i.e. competitive oriented standards that are the driving force for increasing the level of competitiveness of industrial equipment in order to implement the program of its import substitution in the Russian oil and gas industry
Module for description of lines in technological processes of manufacturing gas and oil engineering products
The article substantiates the modular approach to the development of CAD elements for technological purposes, describes the structure of the module, the tools that allow a formalized description of the set of lines of a technological operation and record the results of the description in the design tasks database. A description of a fragment of a design task by the CAD tools in a specialized programming language is considered. A description of the operators of the design task is given, the formal parameters of these are used as formal parameters of the line description operator — masks (formalized description of the string in the operation of the technological process). The expediency of using the description of mask strings in the text of the design task of operators is shown, since at the start of the design task formal parameters in the operators are replaced with their values. This allows to automatically generate a description of the lines of operation of the technological process, the format of which corresponds to the requirements for the preparation of technological documenttation
Simulation of real fluid flow in centrifugal nozzle
The paper discusses calculation methodologies based on using maximum flow principle for centrifugal nozzles, and analyzes both their advantages and disadvantages. Basing on fundamental physical dependencies a mathematical model of viscous fluid flowing through atomizer of centrifugal nozzle is described. The results of research of the influence of atomizer geometry, surface roughness and fluid viscosity on nozzle characteristics are demonstrated. It is also shown that the developed mathematical model for fine spray nozzles calculation allows to obtain the results that agree well to the data of the bench test carried out with water and viscous fluid (till 30 cPz)
The results of studies on monitoring of instrument parameters in the process of metal working are considered. On the example of the process of rolling threads with heads of axial and tangential type, it is shown that the tool can self-adjust to geometric and structural parameters during machining, depending on the systematic and accidental errors that occur when machining each part
Calculation methods to evaluate physical and thermodynamical properties of natural gas. Method of disintegrating incomplete component composition of natural gas into equivalent component composition
The task of adequate evaluation of physical and thermodynamical properties of natural gas in presence of native data on incomplete component composition (in the absence of data on component composition) is solved. Possible solutions are formulated. The investigation of experimental data on component composition of natural gas to identify specific balance of higher hydrocarbons is given. A new calculation method of disintegrating incomplete component composition of natural gas to equivalent component composition for the purpose of further use of calculation methods in existence of evaluation of physical and thermodynamical properties of natural gas on the basis of information about the component composition in computer models, computation of regimes and technological tasks of pipeline gas transport is suggested
Сontrol of complex flow parameters of production wells by measuring system of new generation
The article is dedicated to the solution of the problem of operational control of complex multiphase flows of production wells, characterized by high gas factors and presence of impurities of sand and/or water. It is shown that for a reliable evaluation of the well operation mode it is necessary to carry out complex moni-toring of such basic parameters as the production rate and the dynamics of its change, the component composition, wellhead pressure and the temperature of the extracted production. This information is necessary to select a highly pro-ductive and trouble-free operating mode of the well. For practical implementation of complex monitoring, a low-energy information-measuring system of the new generation «Potok-6» was proposed. The article presents a functional scheme for processing information signals. The time diagrams of the sand registration chan-nel operation are presented and the advantages of new technical solutions are specified
Influence of external electric field on permeability of charged porous layer
On the basis of the cellular model of porous medium and thermodynamics of irreversible processes (Onsager approach), a new method for calculating the flow of solvent (water) and electric current flowing through a charged porous layer (membrane) under simultaneous action of an external pressure gradient and electric potential is proposed. It is shown that the total permeability of the porous structure both due to filtration and due to the electroosmotic transfer of the solvent increases with the electrolyte concentration
Synthesis and antioxidant activity of phenolic derivatives with heterocycles fragments
The synthesis of 2-(2,3-dihydroxybenzyl)-1H-isoindol-1,3(2H)-dione was descri-bed. The structure of synthesized compound was confirmed by IR- and NMR-spectroscopy. The way of electrophilic attack of catechol ring depends on the solvent, as it was shown by quantum-chemical calculations (Gaussian09 program, semi-empirical method PM6). In case of substitution at the third position in catechol ring the energy of cationic intermediate is lower in chloroform than the one in methanol. As the reaction proceeds on the way of energy minimum, it afforded the 3-substituted product. Energy of dissociation of ArO-H bond was calculated to reveal possible antioxidant activity of target compounds using quantum chemical method (semi-empirical PM6). The ability of synthesized compounds to destruct cumene hydroperoxide was studied. It was estimated, that 2-(2,3-dihydroxybenzyl)-1H-isoindol-1,3(2H)-dione, 1-(4-hydroxy-5-isopropil-2-methylbenzyl)azepan-2-one and 1-(4-hydroxy-5-isopropil-2-methylbenzyl)pyr-rolidin-2-one possess the best antioxidant effect
